If you are more of a casual player then Oras would be fine. The big thing is missing out gen 7 and z moves

Usum would be better if you play online more or you play competitively. There is only so much you can learn about competitive if you play the same people (I’ve battled my sister so many times I can generally predict what she does fairly easy)
